This invention relates to a device for locking the spring-operated coverof a lighter, and for releasing said cover when the lighter is to beused.

A lighter is known which comprises a casing having a bayonet slot forlongitudinally guiding a bolt, which cooperates with a protruding tongueof the cover and can be coupled with said tongue by being given a smallturn.

As distinguished from the lighter described above, the essential featureof the present invention is a push of variable length, which protrudesoutside the lighter casing and is pivotally movable towards it foroperating a latch which is pivotally mounted in the casing, the sidewall or" the casing between the push and the latch having an openingwhich permits of the inward movement of the push only when the latterhas been reduced to its smallest length.

An embodiment of the lock is illustrated, by way of example, in thedrawings, in which the parts constituting the lock are shown inconjunction with other lighter parts.

Fig. l shows the lock in its normal, closed position.

Fig. 2 shows the same lock during the releasing operation. Both drawingsare longitudinal sections.

One of the narrow side walls of the lighter casing I has a longitudinalslot 5, adjacent to which a push 2 is provided outside the casing. Thispush is connected with the casing by arms I and a pivot pin 9 mountedinside the casing. The push 2 consists of a sieeve, within which thepush bolt i is longitudinally movable. A spring 3, provided in thesleeve below the push bolt il, continuously urges the push boltupwardly. The side wall of the push sleeve 2 facing the lighter casinghas at its upper edge an opening lil, with which the enlarged head ofthe push bolt 4 is in register when the bolt is depressed. The presenceof this opening permits of making the other walls of the sleeve longerso as to provide a long guideway i'or the bolt even when the latter isnot depressed. A narrow, tongue-like latch 8 is provided within thecasing I. This latch is also pivotally mounted on the pin 9, and isurged into its locking position by an expanding spring 8. An angle stopII, protruding inwardly from the narrow side wall of the casing I,serves for limiting the pivotal movement oi" the latch.

When the lighter is out of use, the head of the push bolt 4 bearsagainst the side wall of the lighter. In order to release thespring-operated cover (which is not shown in the drawings), the pushbolt 4 is depressed and subsequently the push 2 pressed towards the sideWall of the casing so that the bolt head, fitting in the opening for usewith a latch for a spring operated lighter cover, said latch mechanismrelease means comprising a push of variable length pivotally connectedto said casing and protruding out of a lateral opening in a casing wall,said push being adapted to be pivotally moved inwardly through saidopening, for operating said latch so as to release said cover, when andonly when said push has been reduced to its smallest length.

2. In a latch mechanism release means adapted for use with a latch for aspring operated lighter cover, said latch mechanism release meanscomprising a sleeve pivotally connected to said casing and. protrudingout of a lateral opening in a casing wall of the lighter, and a boltprotruding out oi the upper end of said sleeve and adapted to bedepressed against the force of a spring, said sleeve and bolt beingadapted to be pivotally moved inwardly through said opening, foroperating the latch so as to release the cover, when and only When thebolt is depressed.

3. In a latch mechanism release means adapted for use with a pivot-pinmounted latch for a spring operated lighter cover, said latch mechanismrelease means comprising a push of variable length protruding out of alateral opening in a casing wall of the lighter said push beingpivotally connected to the casing by means of the pivot pin mountingsaid latch, said push being adapted to be pivotally moved inwardlythrough said opening, for operating the latch so as to release thecover, when and only when the push is reduced to its smallest length.
